Overview

PDF is seeking a Sr. Optics Engineer in Electrical Beam Optics to drive the R&D, manufacturing, and delivery of state-of-art Electron Beam Inspection systems designed by PDF Solutions, eProbeTM, for use at 300mm semiconductor wafer fabs for use in yield ramp and manufacturing control. The Optics Engineer must be a highly motivated and a self-driven team player with strong communication skills and possess the drive to deliver quality results on time in a dynamic, multi-discipline, intensive and highly productive environment.

Responsibilities

• Work closely with PDF internal engineering team towards delivery of electron beam columns for next generations of eProbe systems
• Simulate existing column designs under their full space range of operation. Match simulations to experimental data, refine model parameters of the simulation, and refine models of ebeam source.
• Use simulation to drive new modes of operating the column e.g. with added lenses and deflectors.
• Design and simulation in 3-D packages for non-rotationally symmetric column elements such as Wien filters and high-precision energy filters
• Hands-on work with on PDF’s Ebeam tool for column characterization

Qualifications

• Masters/PhD in Electrical engineering, physics, material science, or similar engineering field
• Strong experience in e-beam optics simulation preferably with Munro’s code
• Experience in any scripting or programming language (e.g. Python, Java, C#, C )
• Experience with any data analysis package (e.g. Excel, MATLAB, R, JMP)
• Good analytical and engineering skills
• Good written and verbal communication skills

• Other desirable Skills and Experience
  • Experience or familiarity with 300mm semiconductor IC manufacturing
  • Experience or familiarity with semiconductor capital equipment, especially ebeam and ultra-high vacuum equipment.
  • Experience specific to ebeam ‘inspection’ columns and, even more so, in ‘voltage contrast inspection’ column is very desirable.
• Hand-on experience in bringing up new ebeam columns, ebeam guns, ebeam electronics and ebeam test fixtures for characterization.
